|These four games will test
your knowledge of Inventions and what you learned while viewing our
site. The Crossword will give you clues to the inventions, and you
will have to fill in the blanks. For the quiz, obviously you will
be quzzed on what you read; and for Hangman, you will guess letters,
and the answer will be an invention that we have explained. Do your
best and have a grat time!
